Space journalist Richard Hollingham travels to the US to find out what goes on inside the workshops and hangers of the Mojave Desert. He meets engineers and rocket scientists attempting to create a new industry of private space flight and discovers rockets, planes and a culture in which risk is encouraged. If the projects being developed in this small desert town are successful, they could ultimately transform access to space and make a difference to all our lives.

New series 1/4. A comic but scientifically accurate look at the science and history of space exploration. Today: how we might one day travel to Mars and beyond, and the problems of long space voyages, with tips on a rather unsavoury way to stop cosmic rays.
